ABSTRACT
Recent interest in the volatilization of selenium (Se) is related to the buildup of Se in soils, which potentially poses risks to the health of humans and wildlife. Selenium may accumulate to toxic levels in many areas of the world. In the Kesterson Reservoir of the San Joaquin Valley of California, Se has accumulated to such high levels that it has been responsible for death and deformities in the wildfowl population. There is concern that the Se content of some crops might increase to levels high enough to jeopardize human health [1]. Thus, the agricultural management of Se-contaminated soils is of major importance.
